Abstract

In this paper, the non-linear analyses of beam deflection were used to calculate the modulus of elasticity of stainless steel (grade 410) beams that exposed to heating and then cooling with different rate. Several specimens of alloy steel were heated to temperature above critical temperature AC3 at iron-carbon diagram (about 920Co) and then cooling with different cooling rate by using various cooling media. The cooling rates were (0.11, 1.2, 17, 77 and 150oC/Sec).
